class Dog
private int teeth_number;
private boolean isMad;
private String name;
private int size;

public Dog(String s,boolean ad,int si)

public String showName()
return name;

public int showteeth()
return teeth_number;

public class TestDog
public static void main(String[] args)
Dog mydog=new Dog("Rocky",false,50);
System.out.println("name : "+mydog.showName()+" teeth number : "+mydog.showteeth());

In the Dog's constructor we don't initialise teeth_number.Then how we get the value 0 for it when we create Dog object?

All fields have a default value: in the case of numbers 0. This doesn't apply to local variables.
I agree. Here's the link:
